Title: Process and apparatus for preparing organochlorosilanes
IPC: C07F7/16
Filed: 1961-11-10
Abstract: A continuous process for the preparation of organo chlorosilanes comprises the passage of an organic chloride through a fluidized bed comprising fluidizable silicon particles while additional silicon is fed to the fluidizable bed, wherein the added silicon has an average particle size greater than the average particle size of silicon particle in the fluidized bed and wherein at least a portion of the silicon of the fluidized bed is comminuted at least intermittently in a non-oxidizing atmosphere to maintain a substantially constant average particle size in the fluidized bed.  The organo chloride may be saturated or unsaturated, aliphatic, cycloaliphatic or aromatic, preferably chlorobenzene, methyl chloride and ethyl chloride.  The silicon in the reactor generally has an average particle size from 20-200 microns.  The added silicon generally has an average particle size of at least 1-2 times the average size of the particles in the fluidized bed.  Preferably powdered copper is mixed with the silicon powder in the range of 0.5 to 20% by weight.  The copper powder may be partially coated in copper oxide, and has an average particle size from 1 to 20 microns.  A promoter, such as zinc metal, may be also employed with the silicon copper.  The ratio of organo trichloro silane and diorganodichlorosilane, in the product, is maintained below 0.35.  The apparatus is operated by: introducing into reactor 10 through line 37 a fresh powder mixture of silicon copper, which is heated by the heat transfer coil 12 to a temperature of 250-350 DEG C.  Methyl chloride is introduced through line 27, the superheater 28, and valve 30 into reactor 10 at a rate sufficient to fluidize the powder.  The mixture of unreacted methyl chloride, methyl chlorosilanes and some powder particles leave through line 16 and enter separator 17 from which some particles return to the reactor, the remainder of the materials <PICT:0988709/C3/1> passing through filter 20 via line 19, where finer particles are separated from the vapours which then pass to conductor 22 and to distillation column 24 from which unreacted methyl chloride is recycled, and from which the organochloro silanes are collected. During the continuous operation, a portion of the powder 39 is bled through valve 36 to a fluid energy mill 31.  This also receives methyl chloride vapour from superheater 28 through valve 32 and guiding jets 34 at sonic speeds which causes comminution of the powder.  The powder is then returned to the reactor via line 15.  Modifications to the apparatus include substituting for the external fluid energy mill a plurality of jets inside the base of the reactor so that the high speed of the vapour produces continuous comminution of a portion of the powder.  In other modifications various mills may be employed, or alternatively part or all of the silicon-copper powder mixture may be completely removed from the reaction stream and comminuted.  Specifications 542,655, 590,654, 626,353, 637,941 and 645,314 are referred to.

Abstract: 1,014,067. Hasp locks. C. W. CHENEY & SON Ltd. Oct. 16, 1964 [Oct. 18, 1963], No. 41155/63. Heading E2A. A key operated lock for articles of luggage comprises a casing containing a linearly slidable bolt 14 which is spring urged for engagement with a hasp part, a locking plate 23 provided with pivot means 24, an aperture 27 and a key engaging projection 29 the latter projecting into the aperture from a part of the margin thereof most remote from the pivot means. In the construction shown the casing comprises front and back plates 5, 6 the front plate 5 having a skirt 8 and four tabs 7 which extend from the skirt and are bent over the back plate 6 to secure the two plates together. The bolt is a pressing in the form of a shallow tray and it has a catch portion 16 which projects partly across a hole 10 in the front plate so that the catch portion 16 can engage a loop 11 of the hasp 12. An end portion 17 of the bolt protrudes from an aperture 9 in the front plate to enable the bolt to be moved by hand against the bias of the spring 18. The pivot means of the locking plate is a hole 24 which is engageable with a part 25 plunged from the back plate 6 and the movement of the locking plate is limited by lugs 26 struck up from the back plate. The locking plate is retained in its locking and unlocking positions by a tail 22 of the spring 18 which is engageable with one or other of two concave recesses 31, 32. In the locking position an edge 33 of the locking plate engages a lug 20 of the bolt to prevent movement of the bolt. The key passes through a pressing 34 which is mounted in an aperture 28 of the front plate and its bit is engageable with the projections 29 to move the locking plate between its two positions. In the construction shown the bolt is moved to releasing position by pressing the portion 17 towards the hasp but in a modification the bolt is moved to releasing position by movement in a direction away from the hasp. This is achieved essentially by rotating the casing and its contents through 180 degrees relative to the hasp and providing a hole in the hasp through which the key can engage the bolt and an additional manipulating member at the bottom end of the bolt which is arranged to protrude from the casing.

Abstract: 1,163,722. Steering by differential braking. INTERNATIONAL HARVESTER CO. 16 Sept., 1966 [9 Dec., 1965], No. 41403/66. Heading B7H. [Also in Division F2] In a braking system for a vehicle (Division F2) having a pair of transversely spaced wheels 12, 14, individual brake pedals 28, 30 are associated with respective brake means for each wheel of the pair such that actuation of one brake pedal effects consequent braking of one wheel only to produce a steering action and actuation of both brake pedals with the consequent braking of both wheels produces a stopping action. In the embodiment shown in Fig. 2, a pair of master cylinders 36, 38 are associated with brake pedals 28 and 30 respectively to supply fluid under pressure via a control valve 52 to the wheel brake cylinders associated with the wheels 14 and 12 respectively. The control valve 52 is provided with a sliding valve portion 70 (Fig. 3, not shown) of a plunger 72 which is normally in a retracted position to cut off communication between the master cylinder outlet conduits 48 and 50 and the brake lines 64, 66 respectively. The plunger 72 is kept in its left-hand position as shown in Fig. 2 when the brake pedals 28 and 30 are not depressed by means of arms 82, 84 forming latches secured to the brake rods 44, 46 and adapted to retain the plunger 72 in its left-hand position by means of a stop member 90. If the operator depresses one of the brake pedals, for example 28, the master cylinder 36 is actuated and hydraulic fluid is forced through the conduits and passages to apply the brake means 32 associated with the wheel 12. In these circumstances the arm 82 on the rod 44 is moved rearwardly but the other rod 46 is retained in its retracted position which, acting through the arm 84 retains the plunger 72 in a retracted position so that passages in the valve block 52 are cut off from communication with each other and only the brake means 32 is applied. When the right brake pedal 30 is applied, the arm 82 retaining the plunger 32 is retained in its retracted position and the passages in the valve block are cut off from communication with each other so that braking effect is applied only to the brake means 34 and the right driving wheel 14. When the operator wishes to provide a braking action as opposed to a steering action in which both driving wheels are to be braked, both brake pedals 28 and 30 are actuated simultaneously and both brake rods 44 and 46 are actuated to move the arms 82 and 84 thus releasing the holding effect on the plunger 72 and the latter is moved to an advance position by a compression spring 78. In this position of the plunger 72 the cross passages 48 and 50 in the valve block 52 are put in communication so that hydraulic fluid is transmitted to both of the brake lines 64 and 66 to actuate both brakes 32 and 34 simultaneously and with an even force.
